Thunder Laser Mini 60 with Chuck style rotary. Thunder documentation states that it runs 4000 steps per rev. I can see that setting in Machine Settings. The object I want to engrave is 55.5mm in diameter. My setup looks like this:
I have a rectangle that measures 231mm wide and 174.3mm high. When I click “Frame”, I expect it should make one single complete revolution, but it revolves approximately 1.6 times. No matter what settings I change in the rotary setup, it does the same thing. I’ve set the steps per rev to 400, and I’ve set it to 10000, and the result is identical.
